To all whom it may concern:

Be it known that we, ARTHUR Tnsvon DAWSON, knight, and GEORGE THOMAs BUCK- HAM, both subjects of th'e King of Great Britain, residing at 32 Victoria street, West.-

minster, in the eountyof London, England, have invented certain new and useful Improvements in or Relating to Pedestal Gun- Mountings,ro'f which the following is a Specification.

This invention relates to pedestal gun mountings of the kind in which there 'is provided aclamping device comprising a furnished with suitable means whereby it can readily either be tightened against the training worm wheel to hold it rigid with the pedestal, or can be slakened so that relative movement can take place between the said worm wheel and the pedestal and the gun be thus rendered capable of being moved rapidly through large training angles. According to the present invention we so construct a pedestal mounting of the above stated kind that the clamping band is arranged inside the pedestal instead of outside asheretofore. The said band is adapted to be operated by a handle or the like arranged externally with regard to thepedest-al. The training worm wheel with whichthe clamping band ooperates may be provided with a boss which is disposed between the pedestal and the center pivot of the gun. By reason of this arrangement tli'e clamping band is effectively protected by the pedestal from injury resulting from blows and the influence of the weather'. Q

In order that the said invention may be clearly understood and readily carried into effect we will describe the same more fully with reference to the accompanying drawings, in whichz- Figure l is a. sectional elevation and Fig. 2 a horizontal section taken approximately on the line 11 of Fig. 1, showing a constructional form of the invention.

. A is the pedestal mounting, B is the training worm wheel and B its boss, C is the 5 clamping band adapted to engage with said boss. The boss B of the worm wheel is dis used between the pedestal A and the bush a or the center ivot of the gun, and the clam ing band which surrounds the said boss is provided with a strip c, the lug o' of and' that is attached to the pedestal and 1s.

which is disposed in a recess a in the pedestal. through the pedestal, and' the lug c and .retains the clamping band C in 'posit-ion.

The free ends of the said band are provided With' strips C2, C2* having` lugs 0"', c" through'which and through the pedestal` passes a horizontally arranged bolt D. The said bolt may be reduced in diameter shown in Fig. 2 toform a 'shoulder (l which bea-rs against the lug c2. The said bolt may be provided with a key d which engages in a corresponding key-way in the lug c2. One end of the said bolt is formed with a knuded head Z2 which projects beyond the face of the destal and providesfor the ready withiiawal of the bolt D when required. The other end is screwthreaded to receive an internally screw threaded sleeve (if, lo the outer end of which an actuating handle or lever Dx is attached, the said handle o r lever being situated outside the pedestal as shown. The bolt D and the screw 'threaded sleeve d* are supported in bearings E, the latter being secured to the pedestal. The angular movement of the said handle or lever Dxbin one direction causes the lugs C. c to move toward each other to tighten the clamping band C on the boss B', and in the other direction allows them to separate so as to slacken -the said band from the boss.

What we claim and desire to secure by Letters Patent 'of the United States is 1. In a gun mounting, the combination with the pedestal and the training` worin wheel, of a. clamping band engaging with the said worm wheel and arranged inside the pedestal, and means arranged taugen tially to said band and carried by the pedestal for tightening and slackening the said clamping band with respect to the lworin wheel.

2. In a gun mounting, the combination with .the pedestal and the training worm wheel, of a boss on the said worm wheei, a clamping band engaging with the said boss 'and arranged inside the pedestal, and means arranged tungentinlly to said band and cany riedy by the pedestal tor tightening and slnckeningr the said clmupin;r band with respent to the boss. y,

3. ln a gun mounting. the combination with the 'pedestal und thc training worin wheel. o? a rlsuupiug band engaging 'with the said worin 'zrlwcl und arranged inside A screw threaded. pin C passesthe pedestal, `means' arranged tangentially to said band and carried by the pedestal for tightening and slackening the said clamping band with respect to the Worm Wheel, and a handle on the exterior 'of the pedestal OI. operating the said means.

4. In a un mounting,' the combination with the pedestal, the center pivot of the gun and the training Worm Wheel, of a boss on the said Worm Wheel arranged between the pedestal and the center 'pix/ot, aclaipp-A ing band engaging With thel said boss and arranged inside the pedestal, and means arranged tangentially to said band and carried `by the pedestal .for tightening and slackening the said lainpingband With respect to the boss of the ,training yyorm Wheel.

` band 5. In-:a gun mounting, they combination' with the pedestal, the center'pivot of the gun and the training Worm WheeL'o a boss on the said Worm Wheel arranged between the pedestal and the center pivot, a clamping band engaging With the said boss, and

arranged inside ther pedestal, means arranged tangentially to saidband and carried by the pedestal` for tightening and' slackening'the said clamping band with respect to the said boss of thetraining Worm Wheel, and a handle on the exterior of the pedestal tfor operating the said means.

46. In gun mounting, the combination with the pedestal andv the training `Worin,

Wheel, of a clamping band engaging Withl the said Wormsvlieel and arrangedfin'side'the pedestal, means for attaching `the' said clamping band to the pedestaL-tv'vo free ends of the said band, and means arranged tangen tially to said band and carriedby the pedestal for .causing the sai'd free ends. to appreach` and recede to tighten and slacken the with respect to the` training Worm Wheel. y

7. In a gun mounting, the combination with the pedestal and the training Worm wheel, of a clamping band engaging with thesaid'worm Wheel and arranged inside the pedestal, means for att hing the said 'clampingband to the pedesta two free ends of said band, a bolt passing through the said free ends, said bolt being arranged tangentially t0 said band and being carried by the pedestal for tightening and slackening thel said clamping band with respect to the.

Worm Wheel, and a handle on the exterior of the pedestal4 for actuating the said bolt.

8. In a gun mounting, the combination with the pedestal andthe training Worm Wheel, of a clamping band engaging with said Worm wheel and arranged inside the pedestal, means for attaching said clamping band to the pedestal, two free ends of said.

band, a bolt passing through 'said free ends tangentially to `said band, an internally screw threaded .sleeve engaging With said bolt and projecting at one end beyond the pedestal, bearings supported by the pedestal for said bolt and sleeve, projecting end of the screw-threaded sleeve ifor tightening and slackening the said clamping band with respect to the Worm Wheel.

9. In a' gun mounting, the combination with the pedestal and the training worm Wheel, of a ring of armor at the upper end of said pedestal, a boss on said worm wheel disposed inside said ring,a clamping band engaging with said boss, a lug on the clamping band disposed in a recess `in the ring, a pin passing vertically through the ring and through the lug, two free ends of said band, a bolt passing through said free ends, and a handle onthe exterior of the pedestal for ace;v

tuating said bolt. l ln testimonyrwhereof we alii; our signatures in presence of two Witnesses.
